Motion checker provides palm-sized control

Stepper Motor ControllerMCH-2 Motion Checker is a palm-sized plug-and-play stepper motor controller that has a built-in constant voltage driver. Front panel controls allow constant speed motion or trapezoidal motion with programmable low and high speeds, as well as ramp-up/down times. Motion profiles can be set to run indefinitely or for a set number of times. The built-in driver is intended for tin-can type stepper motos and is available in a bipolar (400 mA rated, 700 mA peak) or unipolar (2.5 mA rated, 400 mA peak) driver configurations. A separate CW/CCW output allows for attachment of an external driver.
